Let A represent Press A and let B represent Press B.
So, they own 14 total presses. This means that:
They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:

Substitute this into the second equation: "
First, we can divide everything by 5 to simplify things:
Distribute the left:
Combine like terms:
Subtract 196 from both sides:
Divide both sides by -3
So, the company has 5 Model B presses.
Which means that the company has 14-5 or 9 Model A presses.
And we're done!
